Subject: [PATCH] Bug 6950: Make the resort working when searching for a tag

If you click a link from the Tag Cloud, the results page offers the
usual select menu to resort your results. However, doing so resubmits
the search as a standard keyword search.

Test plan:
1/ Click on a tag
2/ Use the resort dropdown list to change the sort
3/ Confirm that the results are relevant.
